Maintenance
Recommended Periodic RL (LM Version) Circuit Breaker
Inspection Procedure
A suggested procedure to follow during
Periodic Inspections:
1 . De-energize the primary and control circuits.
2. With the cubicle door closed, rack the circuit breaker to the
DISCONNECT position.
3. Open the cubicle door, and remove the circuit breaker from
the cubicle.
4.
Rotate the racking screw to the TEST position
(approximately 3 turns) to clear the spring discharge
interlock, before attempting to charge closing springs.
Exercise the circuit breaker through several close-open
cycles. For electrically operated circuit breakers, operate the
circuit breaker electrically. (Refer to the specific w1nng
information for your circuit breaker to determine where
control voltage signals should be applied. Usually, spring
charging
power is connected between secondary
disconnects SD12 and SD16, closing control power

Throughout this manual, references to RL-800 etc (unfused) also
apply to RLF-800 (fused) versions.
Notes:
1 . Any circuit breaker which has interrupted a heavy fault
current should be inspected according to the recommended
procedure for maintenance and lubrication.
2. "LM" indicates Low Maintenance RL Breaker produced
beginning June, 1991
between SD13 and SD16, and tripping power between SD11 and
SD16. Secondary disconnects are arranged with SD1 on top, and
SD16 on the bottom). Examine the operation of the circuit breaker
during these operations for any evidence of difficulty, erratic
operation, etc.
5. Test the tripping system, using an appropriate test set, such
as the Siemens Portable Static Trip Test Set, model PTS-4. Refer
to 'Static Trip Ill Information and Instruction Guide', SG-3118, and
'Portable Test Set Instructions', SG3138, for information on testing.
The test should include tripping of the circuit breaker by the trip
device. This confirms the functionality of the system, including the
trip device_and the tripping components.
6.
Clean any accumulation of dust or dirt from the circuit
breaker. For insulated parts, use a clean lint-free cloth. A non-toxic
cleaner, such as denatured or isopropyl alcohol may be used.
7.
Turn the racking screw to the DISCONNECT position, and
reinstall the circuit breaker in the cubicle.
